Communication has been a focus for Penn State's secondary early in head coach James Franklin's first training camp and it shouldn't be a major problem for a unit that returns four projected starters with experience.

Senior Adrian Amos will be a three-year starter and he made six starts at cornerback and six at safety last season. The 6-0, 209-pounder is expected to make the full-time move to safety.

Junior corner Jordan Lucas started all 12 games in 2013 and was third on the team in tackles (64) and led the Lions in pass breakups (13).

Senior Ryan Keiser, the likely starter at the other safety spot, played in 11 games last season and made five starts.

Junior corner Trevor Williams made six starts and played in all 12 games a year ago.

"Our eyes all always on them, our eyes are always to the sideline,'' Lucas said in a video posted on GoPSUsports.com.

"Because things change. ... If an offense checks a play, we have to get our eyes to the sideline. And we could be in 'man' coverage, Adrian (Amos) gets the call, he signals us the call and we go from there.''

Defensive coordinator Bob Shoop, who held the same position on Franklin's staff at Vanderbilt, is the man directing the secondary along with cornerbacks coach Terry Smith. Shoop is also coaching the safeties.

"It's critically important. I mean, not just the safeties and the corners but the linebackers,'' Shoop said of communication.

"And a lot of times, based on formations and sets and backfield sets, we might change a support pattern where a safety has the force or a corner has the force or even a 'backer in some cases. And the players need to be aware of all those different things, both communicating them and acknowledging the communication.''

Amos has the physical tools to play multiple positions for PSU. He has the quickness to play corner and the size to handle safety and, possibly, weak-side linebacker. Shoop believes he can be an All-Big Ten player.

"We're communicating in the meeting room, it's just second nature,'' Amos said.

"Just call it out when you see it. A formation comes out, you just call it out.''

"I think our communication is really good,'' Terry Smith said.

"I think there's still some room for improvement.

"We've got a bunch of veteran guys back there that communicate really well.''
